Opaline Well Project
Located approximately 190 km southeast of Port Hedland and 40km west of Nullagine.
Potential for shear hosted gold in the tenement. Similar geology to the 1.25 million ounce Warrawona deposit ~70km to the NE of Opaline Well.
2019 field exploration on the neighbouring tenement by Greatland Gold identified a mineralised corridor which runs directly into the Opaline Well tenement.
Historical rock chip samples in the Project area include 6.32 g/t, 7.95 g/t, 13.7 g/t , 13.22 g/t, 17.0 g/t, 20.5 g/t, 44.6 g/t and 200g/t Au.
A historical base metal rock chip anomaly by Great Southern Mines, adjacent to the historic workings of Opaline Well-2 returned assays of 0.25-1.15% Cu, 0.14-1.85% Zn, 79-155g/t Ag and 0.19-0.41g/t Au. This is proximal to a small gravity high.
A large gravity anomaly lies to the south-east, near Opaline Well-1. There is no drilling at this location and the gravity anomaly is untested.
Triberton Creek gold workings occur at the northern end of the licence and the Opaline Well alluvial gold workings occur in the central licence area.
The general topographic relief of the Opaline Well project is largely influenced by the bedrock geology and is characterised by low hills with strike-controlled ridges to the east. Remnants of preserved c. 3020–2920 Ma De Grey Supergroup are preserved in the east of the project, including unconformably overlying clastic metasedimentary rocks of the Gorge Creek Group. Ultramafic rocks intrude the southern area of the Kelly greenstone belt in the southeast of the project. The Coongan and Kelly greenstone belts hosts several small gold prospects and mines in shear zones parallel to, but offset from, the main shears in the area.
Historical exploration undertaken to date has not effectively tested, nor defined the mineralisation potential of the system, most likely due to low-cost, exploration strategies and the diverse suite of commodities targeted in the area in the last 50 years.
